Description

Technical Field

[0001] This utility model relates to a device for quickly assembling and disassembling a sliding gate hydraulic cylinder, belonging to the technical field of continuous casting machine maintenance equipment. Background Technology

[0002] In the continuous casting area, the sliding gate hydraulic cylinder is one of the most critical pieces of equipment. During the slab continuous casting process, after each ladle of molten steel is poured, the sliding gate hydraulic cylinder needs to be removed from the slide plate at the bottom of the ladle. Currently, the sliding gate hydraulic cylinder is disassembled using a counterweight arm. Due to the significant weight of the sliding gate hydraulic cylinder, relying solely on the counterweight arm to provide upward pulling force is time-consuming and labor-intensive during disassembly. Furthermore, the significant swing of the sliding gate hydraulic cylinder during disassembly poses a risk of collision with surrounding guardrails and operators, resulting in equipment damage and safety hazards. Therefore, it is essential to improve the existing counterweight arm device for disassembling and assembling the sliding gate hydraulic cylinder. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for quickly disassembling and assembling a sliding gate hydraulic cylinder. This device can minimize the swing of the sliding gate hydraulic cylinder during the disassembly process, effectively prevent the sliding gate hydraulic cylinder from colliding with the surrounding guardrails and operators during the disassembly process, and improve the efficiency of disassembling the sliding gate hydraulic cylinder.

[0004] The technical solution to the above technical problem is:

[0005] A device for quickly assembling and disassembling a sliding gate hydraulic cylinder includes a support frame, a counterweight arm, a counterweight arm wire rope, a lifting ring, and a hydraulic cylinder fixing plate. The support frame is located on the outside of the main arm, the counterweight arm is fixed to the top of the support frame, the counterweight arm wire rope is installed on the counterweight arm, the lower end of the counterweight arm wire rope is connected to the lifting ring, the lifting ring is connected to the upper end of the sliding gate hydraulic cylinder, and the hydraulic cylinder fixing plate is fitted onto the upper end of the sliding gate hydraulic cylinder. The improvement is that it also includes a fixed base, a ratchet device, a tension wire rope, and a hook. The fixed base is fixed to the side of the support frame, the lower end of the ratchet device is vertically fixed to the fixed base, one end of the tension wire rope is connected to the ratchet device and is wound around the ratchet device, and the other end of the tension wire rope is connected to the hook, which hooks onto one side of the hydraulic cylinder fixing plate outside the sliding gate hydraulic cylinder.

[0006] In the aforementioned device for quick assembly and disassembly of the sliding sprue hydraulic cylinder, the fixed base and the support frame are welded together. The fixed base is a square plate with anchor holes at each of its four corners. The lower end of the ratchet device is connected to the fixed base via anchor bolts.

[0007] The aforementioned device for quick assembly and disassembly of the sliding gate hydraulic cylinder comprises a ratchet mechanism consisting of a ratchet frame, a ratchet shaft, a ratchet, a pawl, and a handle. The lower end of the ratchet frame is connected to a fixed base. The ratchet shaft is installed in the ratchet frame. One end of the tension wire rope is connected to and wound around the ratchet shaft. The ratchet is fitted onto the ratchet shaft. The rear part of the pawl is fixed to the ratchet frame by a pin. The front end of the pawl is engaged in the teeth of the ratchet. One end of the handle is connected to one end of the ratchet shaft.

[0008] In the aforementioned device for quick assembly and disassembly of the sliding gate hydraulic cylinder, the tensioning wire rope, after being connected to the lifting point of the hydraulic cylinder fixing plate, forms a 10° angle with the horizontal direction.

[0009] The aforementioned device for quick assembly and disassembly of the sliding sprue hydraulic cylinder has a hydraulic cylinder slot on the outer side of the support frame. The hydraulic cylinder slot is placed horizontally, and one side of the hydraulic cylinder slot is fixedly connected to the outer side of the support frame. The sliding sprue hydraulic cylinder is placed on the hydraulic cylinder slot.

[0010] The beneficial effects of this utility model are:

[0011] The balance arm, balance arm wire rope, and lifting ring of this utility model provide lifting tension for the sliding gate hydraulic cylinder. The hydraulic cylinder fixing plate can fix the sliding gate hydraulic cylinder during the lifting process. One end of the tension wire rope is connected to the ratchet device, and the other end is connected to the hydraulic cylinder fixing plate through the hook. Turning the handle can tighten the tension wire rope through the ratchet device, thereby tightening the hydraulic cylinder fixing plate and preventing the sliding gate hydraulic cylinder from swinging during the lifting process. The ratchet device itself has a ratchet and pawl structure with a self-locking function, which can prevent the tension wire rope from loosening.

[0012] This utility model has a simple structure and is easy to use. When disassembling and assembling the sliding gate hydraulic cylinder, it increases the lateral tension to prevent the sliding gate hydraulic cylinder from swinging during the hoisting process. This effectively prevents the sliding gate hydraulic cylinder from colliding with the surrounding guardrails and operators during the disassembly process, avoids safety accidents, and improves the work efficiency of disassembling the sliding gate hydraulic cylinder.

One side of the hydraulic cylinder slot 8 is fixedly connected to the outer side of the support frame 2, and the sliding sprue hydraulic cylinder 7 is placed on the hydraulic cylinder slot 8. The hydraulic cylinder slot 8 is used to store the sliding sprue hydraulic cylinder 7 during maintenance.

There are anchor holes at the four corners of the fixed base 9. The lower end of the ratchet device 10 is connected to the fixed base 9 by anchor bolts.

[0022] Figure 1 , 2The ratchet device 10 is vertically fixed to the base 9 at its lower end. One end of the tension wire rope 12 is connected to the ratchet device 10 and is wound around the ratchet device 9. The other end of the tension wire rope 12 is connected to a hook 13, which is hooked onto one side of the hydraulic cylinder mounting plate 8 outside the sliding sprue hydraulic cylinder 7. After the tension wire rope 12 is connected to the lifting point of the hydraulic cylinder mounting plate 8, it forms a 10° angle with the horizontal direction. The tension wire rope 12 can tighten the hydraulic cylinder mounting plate 8 through the hook 13, preventing the sliding sprue hydraulic cylinder 7 from swinging during hoisting.

[0023] Figure 1 , 2 As shown in Figure 3, the ratchet device 9 consists of a ratchet frame, a ratchet shaft, a ratchet, a pawl, and a handle 11.

The rear part of the pawl is fixed to the ratchet frame by a pin, and the front end of the pawl is engaged in the teeth of the ratchet. One end of the handle 11 is connected to one end of the ratchet shaft. In use, rotating the handle 11 causes the ratchet to rotate via the ratchet shaft. The tension wire rope 12 winds around the ratchet shaft and tightens the hydraulic fixing plate 8 via the hook 13, preventing the sliding sprue hydraulic cylinder 7 from swinging. The front end of the pawl is engaged in the teeth of the ratchet, which has a self-locking function to prevent the ratchet shaft from reversing and to avoid the tension wire rope 12 from loosening.
